ELEcTRIcALLY-IGNITED BURNER.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed February 21, 1910. Serial No. 545,179.

To all whom it'may concern.'

Be 1t known that I, EDWARD J. GoLDLA'r'r,

Aa citizen of the United States, and resident companying drawing, which 'forms a part of my specification.

The objectof the invention is to provide av burner especially intended for use in connection with illuminating gas or vapor, which is so constructed as to adaptit to be connected with any suitable source of electrical energy whereby an intermittent current may be passed therethrough when it is intended to ignite the vapor or gas issuing from the burner, as will be -`ore fully set forth in the following detailed description of the different styles of burner shown in the accompanying drawing used as exemplifies.- tions of my invention.

In the drawing Figure 1 is a vertical sectional view of one style of burner with my improvement the electrodes and burner'- tip being shown 1n full lines. F1 2 1s a similar view of a modified form. Fig. 3 is an elevation, partly in section, of another burner employing my invention. Fig. 4 is a partial. sectional view of Astill another modification. Fig. 5 is a diagrammatic view of one manner of forming an electric circuit to control the burners.

My invention is more especially adapted for use` in connection with the acetylene lamps of an automobile, alljough it is equally as welladapted for other uses, as is readily apparent.

The invention consists in providing a body-portion a, made of suitable insulating material, as for example glass as shown, in which are embedded the electrical conductors or electrodes b, b; the.terminals, in

body-portion or housing c, is provided with the shoulder-portion (Z, which is provided with holes or sockets to receive the plugs e, whose ends protrude beneath the shoulder al, in order to receive the socket-ends f, of the conductors. The electrodes '(3, are led into contact with the plugs c, as clearly shown. Thebody a, is of course provided with the gas-passage or channel g, which terminates 1n or beneath the 'tip c and communicates therewith, and at the bottom terminates in the pipe or gas-tube receiving orifice it, and which is shown screw-threaded to permit its being secured in the usual manner to the gas or4 vapor conduit. The relation between the electrodes o, and the burnentip is such that the former will be presented toward the flat side of the llame and thus not interfere with or come into contact with the flame.

As my invention. is more especially adapted for use in connection with the acetylene or gas lamps of an automobile, I have illustrated, in Fig. a 'method of operating my improvement when applied to the lamps of an automobile. A, A, represent two lamps of anyot the Well-known constructions, provided with my improved burner. B, represents any well known type ot coil or vibrator which is provided with the spring-platinum points as at e', and. j; C, represents suitable batteries; while D, is a switch. Battery or batteries C, are connected up with the` coil B, through line 1, and also through line 2, which connects with line 3, and through switch D, when the latter isclosed. Coil or vibrator B, is also connected up through line 4, with li'ne or conductor 5,'whose ends are preferably rovided with the'plug-receiving sockets 4. as shown in F ig. l. Line 3, also connects'wit-h lineG, whose ends may also be similarly provided with the sockets f, heretofore mentioned. With this method of operation, it is apparent that when switch y D, is closed the coil B, will be energized and the platinum points z', andv j, made to vibrate' and thereby intermittently brought into contact with each other, causing a frequent make and break of the circuit which is flowing through the various wires or leads to the electrodes E, and this making and breaking of the circuit will cause the sparking or arcing at the ends or" the electrodes .0, above the burner-tip c. In themeantime 1t is understood that the supply of vapor or gas has been turned on, so thatthe moment switch D, has been closed, the sparking across the burnertip trom one electrode to the other, will cause ignition.

In Fig. 2, I have illustrated a modified form of my construction. In this tigure, the

terminals or electrodes b, of course terminateI screw onto a supply-pipe leading from somsK l suitable source. This cap op?y collar Z, will also 'serve the purpose of retaining the insulating material in place, asfis readily ap parent from the drawing.

Fig. 3, illustrates another style of burner,

more` especiallyadapted for. use in connection with acetylene, andalso shows a moditied form of the invention. The usual metallic gas conduit m, is used, provided with a diderent' but well known style Lof burner-tip c. In this construction the burner body m screws onto the reduced' screw-threaded portion of the Asupply pi )e n; reducing the pipe n as shown and., escribed, leaves a shoulder on which theinsulating and laterally extending block a',

` rests, surrounding the supply-pipe. By screwing burner m, down onto the pipe n, it is evident that the insulating block a', will also be securely held in place. This block a', is provided with the insulating tubes or conduits o, 0, through which the two electrodes b, take. These tubes or conduits 0, extend u a sutlicient distance to prevent any possibility of the current crossing the space between the electrodes and the metallic burner; and at the same time the electrodes are held in place over the burner-tip as shown; the lower ends of the electrodes preferably extending beneath the member a and terminating in the terminals e, as before described and which are suitably secured in place,

In Fig. Lt, another style of burner is shown in which the manner of insulating and maintaining the electrodes b, b', in position above the burner-tip c, is similar to that illustrated in Fig. 3, except that in this constructionv the electrode-maintaining device with its electrodes is simply slipped onto the burner; as these burners are usually the metallic portion of the body of the burner-when metal is used-as the current made to flow through the conductors and the lower part oi the electrodes would be .short circuited and the burner rendered inoperative; at the same time it is important that the electrodes be sutliciently insulated from each other in the body of the burner or housing, so as not to "present a shorter path of the same or less resistance before the intermittent current reaches the tips ol the electrodes where the spark-gap is produced in the path of the discharged gas.

In applying the invention to an automobile where the gas is stored in a tank or tanks, and the gas conducted to the lamps through suitable conduits, the gas-conveying conduit is brought from the tank up into reach of the operator on the seat and there provided with a valve ot any of the wellknown types, so that the flow of the gas to the burners may be controlled from the seat without leaving the machine. The flow of gas having been regulated, the operator throws switch D-which may be of the usual `push-button type-(also located within reach of the operator while on the seat) causing a current to flow lfrom the battery or batteries through thecoil causing the latinum points to vibrate and thus intermittently mala` c nd break circuit, which'induces the current to spark at the electrode 'tips and ignite the gas.

I have shown the burner made entirely of non-conducting material may be employed; and instead of having the entire burner made of such material, the electrode-containing portion or housing may be made in the nature of a 'sleeve to be slipped over the ordinary' style of burner, as the example shown in Fig. 2; or it may be made in the nature ot' a ring provided with the tlange or laterally extending arms to hold the electrodes into position, as for example shown in Figs. 3 and 4. 'It is also apparent that any style oi burner may be employed and the electrodes be made to contorni therewith, and I do not wish to be understood as limiting myself to the exact constructions shown and described, as it is merely essential to have the portions of the electrodes connected with the gas-conveying portion insulated therefrom, which, as shown, can be accomplished :without having the entire 577,521 K ur A body ofthe burnermadefofnon-current conliousing and terminating at the sparking ducting material. y

What I claim as my invention and wlsli td ing at the opposite ends circuit connecting secure by Letters Patent, isf plugs. 5 As an article of manufacture, a housing EDWARD J. GOLDBLATT.
